SHADE-ROLLER.

Specification of Letters Patent.

Patented June 10,1919.

Application filed July 3, 1918. Serial No. 243,238.

To all whom it may concern Be it known that we, JOHN A. SHARPS and IsHMAEL GUY CUTRIGHT, both citizens of the United States, residing at Buckhannon, in the county of Upshur and State of West Virginia, have invented certain new and useful Improvements in Shade-Rollers,- of which the following is a specification.

This invention relates to shade rollers and has for its object to provide a tubular shade roller having a slotted side for the passage therethrough of the upper end of a window shade, which end is provided with means for retaining it within the roller and the shade in position thereon.

A further object of the invention is to provide a window shade roller made of sheet metal bent into tubular form and having a slotted side through which the upper end of the window shade is inserted and secured, said roller having a permanently closed end with an axial opening for the attachmentpf winding means and a longitudinally slldable shoe for the opposite end which may be removed from the roller and which may be inserted thereinto to any distance and thus permit the roller to be cut to proper length to fit the window.

A still further object of the invention is directed to an improvement in the brackets for supporting the curtain roller, or the means for holding the shade within the I roller and to minor details specifically set forth hereinafter. With these objects in view, together with others which will appear as the descrlptlon proceeds, the invention resides 1n the novel formation, combination and arrangement of parts, all as will be descr bed more fully hereinafter, particularly pointed out n the claims, and illustrated in the accompanying drawings, in which: I

Figure 1 is a long1tud1nal,'sect1onal view of the improved shade roller.

Fig. 2 is an elevatlon of the permanently closed ends of the roller.

Fig. 3 is an elevation of the of the roller.

opposite end Fig. 4 is a cross sectional view of the' roller on the line 44 of Fig. 1.

Fig. 5 is a face view of the sheet metal blank from which the roller is formed.

Fig. 6 is a similar view of the blank from which the shoe forming the removable end of the roller is made.

Fig. is a perspective view of one of the supporting roller brackets, and a Fig. 8 is an end view of the shoe insertible in one end of the roller.

In the drawing, 10 indicates the shade roller of tubular form made from 'a' blank 11 of sheet metal of rectangular shape with a notch 12 cut in each corner at one end. The two side edges of this blank are bent perpendicular to the blank and on the same side thereof, on the dotted lines 13, Fig. 5, continuous with one sideof each notch 12, so that when the blank is finally bent into a cylinder, as in Figs. 1. 3 and 4, these bent edges will form inwardly projecting parallel flanges 14. Within one end of the roller 10 there is inserted a circular block 15 of a thickness equal to the longitudinal dimensions of the notches 12, said block being welded, soldered, or otherwise firmly secured within the end of the roller 10. A

'polygonal perforation 16, here shown as square, is formed in the axis of the block 15, this perforation being preferably larger at its inner end than at its outer end for a purpose to be hereinafter set forth.

'Slidable longitudinally into the opposite end of the roller 10 is a shoe 17 formed of a plate of metal 18, Fig. 6, of rectangular shape with curved corners, rolled, folded cylindrically around a circular block l9, in the periphery of which is cut a longitudinal notch 20. The plate 18 and block 19 are ficient frictional engagement with the inner surface of the roller to cause both roller and shoe to rotate in unison, but when sufiicient longitudinal pressure is applied to the shoe, the latter may be moved to any position within the roller or be entirely removed therefrom. The flanges 14 which extend from the inner face of the fixed block to the nent attachment of one end of the roller to the block 15 and at the opposite end of'the roller by the engagement of the flan cs 14 with the notch 20 of the shoe 17 as c early shown in Figs. 3 and 4.

For the purpose of securely attaching the window shade to the roller without the use of tacks, clips or other fastening means driven into or attached to the roller, a wide hem 21 is formed on the upper end of the shade for its entire width, into which hem there is inserted a square or other shaped rod 25 that extends the full width of the curtain and which has a transverse dimension much greater than the width of the slot 23. The upper end of the shade thus beaded is slid into the slot 23 from one end after the removal of the shoe, the bead being above the flanges 14, so that when the shade is released the Wei ht thereof will draw the bead against the edges of the flanges and so hold the curtain against disengagement from the roller. The shoe 17 .may now be inserted in the end of the roller 10, and the latter will be ready to be hung.

The roller 10 is carried upon two brackets 26 and 27, fastened to the window frame in the usual manner, the bracket 26 being of U-shape, in the varms of which is rotatably mounted a toothed roller 28 about which passes a chain for raising and lowering the roller in the manner set forth in Patent, Number 1,223,837, granted to John A. Sharps on April 24, 1917. The inner end 29 of the shaft carrying the toothed roller 28 is square or of other polygonal shape in cross section corresponding to the shape of the perforation 16 in the block 15 and is inserted in said perforation when the roller is hung. the perforation, because of its gradual increase in width enabling the roller to be moved angularly with relation to its axis for more easily engaging and disengaging the opposite end of the roller with its bracket. 27.

The bracket 27 is in the form of an angular plate, its foot piece 30 being screwed to the window frame and the outwardly projecting part 31 formed with a vertically opening notch 32 into which the pintle 21 of the roller may be dropped. For holding the pintle in the notch 32 and preventing the roller jumping or accidentally being disengaged from the brackets 26 and 27, there is provided a spring plate 33 of angular shape through one arm of which is formed a circular perforation 34: for the pintle 21,

this arm lying against the outer side of the Y 26 and 27.

bracket 27 and held in contact therewith by one of the fastening screws which hold the bracket on the window frame, passing through the other arm of the plate. It is evident that to secure or release the pintle. 21, it is only necessary to spring the plate 33 outwardly beyond the end of the pintle and thus permit the insertion of the roller 10 into and its removal from the brackets The foregoing description and the drawings have reference to what may be considered the preferred, or approved form of our invention. It is to be understood that we may make such changes in construction and arrangement and combination of parts, materials, dimensions. et cetera, as may prove expedient and fall Within the scope of the appended claims.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is:

1. The herein described shade roller comprising a tubular body made up of a blank of sheet metal rolled and having its edges turned inward into flanges spaced to leave a longitudinal slot along one side of said body, a block fixed in one end of said body and having an axial opening adapted to receive a shaft, and a shoe adjustable in the other end of said body and including a cylindrical block with a notch along one side, a trunnion projecting from the axis of said block, and a metal plate wider than the block is thick and secured around said block with one edge flush with the outer face of the block, its ends terminating alongside the notch therein and its other edge carried beyond the inner face of the block and having its corners rounded to produce a skirt adjustably mounted in the open end of said body and held therein by friction.

2. A shade roller comprising a tubular member, a block rigidly secured in one end and fo ming a head, therefor, said block having an axial opening therethrough of polygonal cross section and of gradually increasing width from without inwardly, said opening adapted to engage a shaft of similar cross section adapted to be rotated for rotating the roller. said opening by its diverging shape, permitting the roller to be moved angularly on said shaft relatively to its axial line.

' In testimony whereof we affix our signatures in presence of two witnesses.
